To @Il whom it may concern:

Be 1t known thatv I, GEORGE W. HAVER- STICK, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain newand useful Improvement in Air- Cooling Devices, of which the following is al full, clear, and exact description, such as will enable others skilled in the artto which it appertains to make and use the same, reference beingehadtoth'e accompanying drawings, forming part of this speciiication, in

which- Figure 1 is a longitudinal sectional view of 'a device constructed in accordance with my -lnventlon; Fig. 2` 1s a transverse sectional Another object of my invention is to provide an air-cooling device that is of simple construction and which presents a neat and ornamental appearance. l

Referring to the drawings which illustrate I the preferred 'form of my invention, 1 designates an open-ended hollow shell or casing preferably of cylindrical form, and 2 designates a plurality 'of approximately tubularshaped members arran ed longitudinally inside of said shell. Eac 0 en at its upper side, as shown inFig. 3, and t e op osite ends of said member are par- Vtiall c osed by dams 3 so that the member can old a quantity of water. Themembers 2 can be mounted inside of the shell 1in any suitable manner, the means herein shown for holding said members 'position consisting of two spiders or light'- wei ht castings 4 of skeleton construction. arious ,means could be employed, however, forvretaining the members 2 1n position so that I `do not wish it to be understood that my invention is limited to the construction herein shown.

Water is thrown up over the members `2 by means of a spray or nozzle 5 connected to a supply conduit @y and the shell 1 is provided ad'acf 'it its ends with dams 7 that retain or hold a small quantity of water in the bottom of the shell. An electric fan 8 is arranged inside of the shell 1 adjacent one end ofthe members 2 for the purpose of drawing the warm air in a room into said shell and forcing of the members 2 is l said air over the members 2 and out of the opposite end of vthe shell, the air becoming cooled. and moistened in its passage through the shell by the low temperature of the water with which it comes in contact and also by the evaporation of the Water in the members l 2 and in the bottomolI the shell. I prefer to i arrange a second fan 9 inthe front end of the casing adjacent the front ends of the members 2 and drive said fanfby the same electric motor 10 that is employed for drivinr the fan 8, this being accomplished by providing said motor with a long armature -shaft 11 to which both of the fans are secured. With a construction of this description the fan 8 will o crate to draw the heated air in a room into t e shell 1 and force it over the members 2 so that the evaporation of the water in said members will cool and meisten the air, the fan 9 creating a-suction that helps to draw .the cooled air through the shell and also o erating to torce this cooled air out of t e iront end the casing into lthe room.

I prefer to 'form the water supply conduit 6 from a piece of rubber hose or flexible tubing that can be attached to a water faucet in the room so that fresh water will be supplied continually to the device, ther shell being supplied with a' drain-pipe or discharge-pipe that preferably consists of a flexible conduit V12 that surrounds `the sup ly conduit 6 and enters the lbottom of the sllell 1. As shown in Fig. l, the end of the discharge conduit 1 2 rojects slightly above the bottomof the shel so that a small quantity of water will .always remain in the lower portion of the shell. Ii desired, the shell or casing l can be provided in its interior with tapered ribs or projections 13 arranged in alinement with the members 2 in the u er portion of the 'shell so that the water w ich is thrown onto the inner surface of the shell will drip down into the upper row of members 2. I also prefer to form tapered ribs or rejections 14 the water which is thrown onto the exterior 'of said members can drain down to the proj ections 14 and then drip into the members 2 arranged below same.

The shell or casing 1 is.mounted on a baseiece or stand 15 and is provided with a llandle 16 so that the device can be carried conveniently from one place to another and the shell is made long enough to receive the motor 1() and fans 8 and 9 so that the device will be compact and present a neat appearon the lower sides of the mem ers 2 so that ance. While it is preferable to use members 2 that are open at their upper sides, as shown in Fig. 3, I do not wish it to be understood that my broad idea is limited to such a construction as my invention broadly stated, consists of a cooling device comprising an open-ended shell or casing provided with members on which' water can collect, means for throwing water, preferably in the form of a spray, over said members, and a fan for forcing air over said members so that said air will be cooledv and .moistened by the evaporation of the water on said members.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A portable device for cooling the air in a room, comprising a hollow shell or casing open at both ends, approximately tubularshaped members arranged horizontally inside of said shell and having their upper sides open, means for spraying water on said members, means for causing'water to collect in said members and also,m the bottom of said shell or casing, and means for drawing air intoone end'of said casing, forcing it over said members so that the air will be cooled by the evaporation of the water which collects in said members and in the bottom of the casing, and thereafter forcing saidl cooled air from the opposite end of said casing and distributing it inthe room in which the device is located; substantially as described.

2. A portable device for coolin the air in a room, comprising a cylindrical-s aped shellv or casing open at both ends, horizontally dis-V posed trou hs arranged inside of saidcasing and exten ing longitudinally therethrou h, a nozzle projecting into said casing or throwing a spray of water into same, means for causing Water to collect in the bottom of the casing, and electric fans 'arranged adj'a,

casing which is open at both ends, tubularshaped troughs arranged horizontally inside of said casing and extending longitudinally thereof, means for supporting said troughs, means for throwing a spray of water into said casing so that water will collect in said troughs, a drain-pipe leading from the bottom of the casing for conducting away the Water that overows from said troughs, and means for drawing air into said casing so that it\will be cooled by the evaporation of the water in said troughs and thereafter forcing said cooled air out of said casing and into the room in which the device is located; substantially as described.

4'. A portable device for cooling the air in a room, comprising a cylindrical-shaped shell or casing open at both ends, approximately 'tubular-shaped members arranged horizontally inside of said shell and havmg their upper sides open, dams arranged adjacent the ends of said tubular-shaped members for causing waterto collect therein, damsextendingA transversely of the casing for causing water to collect in the bottom thereof, a pipe extending into said casing and'provided with a nozzle which throws a s ray of water upwardly into the casing, a rain-pipe extending into the bottom of the casing and surrounding said pipe, an electric motor provided with a shaft or armature that extends throu h said casing, and fans connected to said s aft adjacent the o posite ends of the casing; substantially as dlescribed.

5. A portable device for coolin the air in a room, comprisin a horizontal y disposed cylindrical-shape shell or casing open at both ends, approximately U-shaped troughs' GEORGE W. HAVERSTICK.
